ABRADING ELEMENT FOR TIRE-PATCH CONTAINERS.

Specification of Letters Patent.

Patented an. 4, 1921.

Application led May 27, 1920. Serial No; 384,655.

To all Lo/tom it may concern Be it known that I, JESSE A. DUFFY, citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Abrading Elements for Tire- Patch Containers, of which the following is a specification.

rThis invention relates to new and useful improvements in abrading elements for tire patch containers. n

In applying toan inner tube what 1s known as a cold patch it' is first necessary to clean the surface of the tube and roughen the same so that the adhesive will adhere to the surface of the tube. tomar to accomplish this in various manners, and itis quite a common practice to use sandy paper or a holder having a. surface of carborundum or the like` Such devices are open to objection for the reason that the particles of carborundum, sand or the like are usually attached to their supporting surfaces by means of glue or other adhesive and chip off and otherwise deteriorate whereby the abrasive qualities are lost. Also each time such a device is used it becomes less abrasive in its action.

My invention has to do with the provision of an abrasive element which will be of a more or less permanent feature and will include abrasive points of longer life, the entire element being of an integral nature rather than an abrasive material Aglued to supporting surface. Another feature resides in providing the element in the form of an attachment or as a part of a container, the element when combined with the con-` tainer providing a hand tool for roughening tire tubes.

In carrying out the invention in the present instance I propose to form the abrading element of a strip of comparatively thin metal having abrading points punched out therefrom. 'The strip of metal is preferably fastened around a container and at one end of the latter whereby the remainder of the container becomes a handle for holding the tool which is thus formed. However it is not essential that the element be confined to a portion of the length of the container.

The invention will be more readily understood from a reading of the following speci; ication and by reference to the accompany- It has been curf ing drawings, in which an example of the invention is shown, and wherein:

Figure 1 is a side elevation ofa tire patch container equipped with an abrading element constructed in accordance with my invention,

Fig. 2 is a perspective view of the element removed fromv the container, and

Fig. 3 is an elevation of a modified form of the container in which the abrading element forms part of a slip cap for the container.

In the drawings the numeral 10 designates a cylindrical or tubular tire patch container which may be of any approved construction.` This container has the usual bottom 11 and screw cap 12 provided at the opposite end. The particular construction of the container in this instance has nothing todo with the invention as will be evident.

In reducingthe invention to practice I provide a strip of metal 13 and punch out the abrading points 14 on the outer surface of said strip. These points are preferably given a triangular shape but this is not essential. The proximity of the points, one lto another, may be varied in accordance with the work to be done by the element. The length and width of the strips may vary under different conditions. I provide vertical flanges 15 and 16 on the ends of the strip, the flange 15 being returned on the inward side of the strip and the flange 16 being returned on the outer side of the strip. The strip is made of such circumference as to lt snugly around the container 10 when the flange 16 is engaged in the flange v15. By crimping the flanges the element is securely fastened on the container by frictional contact. An offset boss 17 may be provided at the uppermost portion of the strip with its lower end open and given a downwardly converging shape. This boss may be utilized for supporting a pair of scissors A as is shown in Fig. 1, but it is to be understood forms no essential part of the invention.

It will be seen that the strip of metal 13 extends only a portion of the length of the container thus leaving a large portion of the surface of the container free which may be used as a handle and grasped by the user. It will be seen that when the abradmg element is applied to the container a hand tool is provided for roughing the eurace of inner tubes. The abrading points la Will attack the rubber surface and not only clean the same but roughen it so that *a patch will readily stick thereto. It is pointed out that this element will be inexpensive to make and will tend to strengthen the container. Further in this form the element is applied as an attachment, therefore may be attached to any container which has all ready been manufactured. 'Ihe life of the abrading element Will be indefinite as is obvious.

It is quite evident that the abradingelement may be applied to containers in vari-v ous Ways and as a further illustration reference is made to Fig. 3 wherein a modiied form is shown. In this figure a tubular container vIO is shown and provided with the usual bottom ll. The container is shouldered circumferentially at 18 and provided With a reduced collar 19. A cap 20 is Jformed with a suitable top and a sleeve or apron 13 made of metal and provided With abrading points la substantially the same as the structure shown in Fig. 2. In this instance the abrading element forms a sleeve or sides of the cap and lits snugly around the collar i9 so that its lower edge rests on the shoulder whereby it is continuous to the body portion of the container as Will be obvious. The container also has a large portion oi its surface accessible for use as a handle. It is obvious that many modifications could be had Within the scope of the invention.

What I claim, is:

The combination with a tubular container having an exterior curved surface, of a section of sheet metal having abrading points stamped out therefrom and projecting laterally from its outer surface, said section of sheet metal being longitudinally curved to fit the outer curved surface of the container and surround the same, said section of sheet metal having free ends bent to form detachably interlocking flanges, said section of metal being shorter than the container whereby an end portion of the container may be grasped by the hand Without covering said abrading element, said abrading element being adapted to be circumferentially contracted and inserted Within the container for shipment therein.

In testimony whereof I aiiix my signature.

JESSE A. DUFFY.
